Webhook deliveries
If you want to customize your JustAsk deliveries, webhooks may be a good fit. They give you the ability to create context-specific workflows beyond what built-in destinations support.
For example, you could use a platform like Zapier to catch JustAsk webhooks and perform different actions based on data values, such as those for CSV-formatted deliveries.
Requirements
Section titled “Requirements”To successfully use JustAsk webhook deliveries, your webhook must return an HTTP 200 status response upon delivery. A different status could cause delivery retries or failures.
Creating a webhook delivery
Section titled “Creating a webhook delivery”1. Create a webhook URL
Section titled “1. Create a webhook URL”Prior to using webhooks as a delivery destination, you’ll need to create a webhook URL for JustAsk to send requests to. For example, using Zapier’s webhook trigger in a Zap will create a webhook URL for you to use.
2. Configure delivery settings
Section titled “2. Configure delivery settings”- Navigate to a published dashboard.
- Click File > Deliveries & Alerts. The delivery options will display on the left side of the page.
- Fill in the following:
- Delivery — Select Schedule or Alert.
- Send — Select the content to be delivered.
- Destination — Select Webhook.
- Name — Enter a name for the delivery.
If creating an alert, use the Alert tab to define the conditions that must be met to trigger the delivery.
3. Configure the delivery schedule
Section titled “3. Configure the delivery schedule”In this step, you’ll define the cadence for the delivery:
- For schedules, this determines when JustAsk will deliver the specified content to the destination
- For alerts, this tells JustAsk when to check if the current query results meet the conditions required to send the delivery
Schedules can be defined using the visual options or with cron:
Visual schedule builder
Use the UI options (Daily, Weekly, etc.) to select a time period.
By default, schedules are set to send in the local timezone of the delivery creator’s computer. Use the Times are in drop down to change the timezone.
Custom cron schedule (Advanced)
A cron expression is a string that describes the individual details of a schedule:
| Order | Unit | Allowed values | Allowed special characters |
|---|---|---|---|
| 1 | minute | 0-59 | * , - / |
| 2 | hour | 0-23 | * , - / |
| 3 | day of month | 1-31 | * , - / L W ? |
| 4 | month | 1-12 or JAN-DEC | * , - / |
| 5 | day of week | 1-7 or SUN-SAT | * , - / L W ? |
| 6 | year | any | * , - / |
Using cron, you can create schedules like the following:
0 9 ? * * *30 6 L * ? *45 8 ? * MON-FRI *JustAsk uses Amazon Web Services’ (AWS) syntax for cron expressions. Refer to the AWS documentation for more information. By default, the most frequent you can configure a schedule is hourly.
4. Select format and filter options
Section titled “4. Select format and filter options”In the Dashboard or Chart tab, you can:
- Select the format of the content, such as PNG, PDF, XLSX, or CSV
- Lightly customize the contents and layout, such as expanding tables to include up to 1,000 rows, hiding filter values, or arranging tiles in a single column.
- Set filter or control values for the delivery. Some formats will have additional customization options. PDF formats, for example, will allow you to specify the orientation and page size for the PDF.
For dashboard deliveries, the default filters and controls will automatically be applied upon creation. Subsequent default filter value updates will not change the filter values set for existing deliveries.
5. Configure webhook settings
Section titled “5. Configure webhook settings”The last step is to configure the webhook settings. Click the Webhook tab and fill in the following:
- URL - Enter the webhook URL you created in step 1 of this guide.
- File Name (Without extension) - Optionally specify a file name for the delivery, leaving out a file extension like
.png. Mustache references are supported.
6. Test the delivery
Section titled “6. Test the delivery”If you want to test the delivery before saving, click the Test Now button in the bottom left corner of the page. This will send the dashboard/chart to the destination using the current settings. For example, using Test Now would send the delivery to all Recipients.
7. Save the delivery
Section titled “7. Save the delivery”When finished, click Save to create the delivery.
Request formats
Section titled “Request formats”The type of delivery JustAsk sends determines the format the request body will take:
Link-only
Section titled “Link-only”JustAsk will send a POST request with a JSON object in the body that contains:
{ "url": "<dashboard_url>"}All file formats
Section titled “All file formats”JustAsk will send a POST request with the file content directly in the body using streaming delivery:
- Headers:
Content-Type- Appropriate MIME type (text/csv,application/json,application/pdf,image/png, etc.)Content-Length- Size of the file in bytes (when available)X-Filename- Original filename for reference
- Body: Raw file content streamed directly
